KNOB ATTACHMEN'T.

SPECIFICATION forming'part of Letters Patent No. 350,397, dated October5, 1.856,

Application filed January 9, 1886. Serial l\lo. 181,124.

To all whom it may concern:

Be it known that I, JOHN Sermon, a citizen of the United States,residing at Stamford, in the county of Fairfield andStateof'Oonnecticut, have invented certain new and use fulImprovcmentsiu Knob Attachments; and- I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had tothe accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure '1 of the drawings is a representation of the devices embodyingmy invention,and is a side view of a door-knob and spindle, a portion ofthe former being in section. Fig. 2 is a cross section taken on thebroken line as m, Fig. 1. Fig. 3 is a side view of the eccentric bolt.Fig. 4 is a cross-section of said bolt on the broken line y, Fig. 3.

My invention has relation to devices for attaching knobs to theirspindles; and it con sists in the construction and novel combination ofparts, as hereinafter set forth, and pointed out in the claims.

Referring by letter to the accompanying drawings, A designates thedoorknob, B the knob-shank, and G the spindle, which spindle isrectangular in cross section. The seat D in the knob-shank is alsorectangular in cross- At one side ofthe spindle-seat D, I provide a camseat or hole, E, in which I fit an eccen (No model.)

different thicknesses, for the reason that the cam-bolt will lock thespindle in its seat at any point of its length. a

The upper and lower ends of the cam-bolt are cylindrical incross-section, having journals which may be readily turned in theirseats.

The metal on or at the edge of the hole or seat E is prepared to preventthe cam bolt or pin F from falling out when not attached to the spindleby spinning or turning over the edge of the metal around the pin.

I attach importance to the employment of the cam-bolt and to the factthat the spindle is of the ordinary construction, not being notched norrecessed. I

I am aware that knob-shanks have heretofore been provided with threadedapertn res, knob-spindles notched and recessed, and tapering screwsemployed to fasten the knobs to the spindles, and therefore do not claimsuch devices broadly.

Having described this invention, what I claim, and desire to secure byLetters Patent,
